When the user uses his feet to apply a force to move the swing rod 33 upwardly, the second cable 54 can be moved to pull the at least one of the second elastic cords 42, so that a leg extension exercise can be performed. Referring to FIG. 15 , in combination with FIGS. 1 and 8 , an abdominal crunch exercise can be performed by the user after being seated on the seat assembly 25 facing the support post 123 with his feet stepping on the base member 11.

Referring to FIG. 16 , in combination with FIGS. 1 and 10 , the seat frame 20 is first pivoted to an angle of 90 degrees relative to the base member 11, after which the upper pull rod 62 is connected to the second end of the auxiliary cable 57. The user then stands on the base member 11, and with his hands pulling down the upper pull rod 62, a triceps push down exercise can be performed.

FIG. 17 illustrates an assembly similar to that of FIG. 16 , but with the handles 61 connected to the first ends 522 of the first cable sections 521 of the first cables 52. Afterwards, the user stands on the base member 11, and with his hands gripping the handles 61, the user's arms can then pull the handles 61 to perform a standing bicep curl low pulley exercise. The user may also use one hand to grip one handle 61 so as to perform a one arm bicep curl low pulley exercise; may use two hands to grip one handle 61 to perform a standing close grip bicep curl exercise; or, may use one hand to grip one handle 61 and with his body slanting relative to the fitness exercise apparatus 100 to perform a cross body bicep curl exercise. Further, the user may stand facing away from the support post 123 to perform a reverse standing bicep curl exercise, or may stand facing the support post 123 to perform a standing low pulley cable fly exercise. The above exercises differ only in training the different parts of the user's body, so they are not shown here.

FIG. 18 illustrates an assembly similar to that of FIG. 17 , but with the first end 522 of the first cable section 521 and the first end 525 of the second cable section 523 of each first cable 52 being interconnected, and with the handles 61 being connected to the second ends 527 of the second cable sections 523 of the first cables 52. As shown, with the user standing on the base member 11 and with his hands gripping the handles 61, the user's arms can then pull the handles 61 downward to perform an alternating straight arm pulldown exercise, or a standing straight arm pulldown exercise (not shown).

FIG. 19 illustrates an assembly similar to that of FIG. 17 , and as shown, the user stands on the base member 11 facing away from the support post 123, and with his hands gripping the handles 61, the user's arms can then pull the handles 61 to perform a reverse standing bicep curl low pulley exercise.

FIG. 20 illustrates an assembly similar to that of FIG. 17 , but with the user standing on the base member 11 in a slant manner and with his one hand gripping one handle 61, the user's arm can then pull the handle 61 upward to perform a cross body bicep curl exercise.

FIG. 21 illustrates an assembly similar to that of FIG. 17 , but with a left one of the handles 61 connected to the second end 527 of the second cable section 523 of the first cable 52, and with the first end 522 of the first cable section 521 and the first end 525 of the second cable section 523 of the first cable 52 being interconnected. In this way, with the user standing on the base member 11 and with his hands gripping the handles 61, the user's arms can then pull the handles 61 to move toward and away from each other in an up-down direction to exercise both hands of the user.

FIG. 22 illustrates an assembly similar to that of FIG. 18 , but with the handles 61 respectively provided with an extension strap 65. As shown, with the user lying down on the base member 11 and with his feet hooking onto the handles 61, an alternate leg pulldown exercise can be performed.

It should be noted herein that, when the lower pull rod 63 is connected to the first end of the auxiliary cable 57 and the user is seated on the seat assembly 25, a rowing exercise can be performed by the user (not shown).

Referring to FIG. 23 , the second embodiment of the fitness exercise apparatus 100′ of this disclosure is shown to be identical to the first embodiment, and differs in that the second ends 524 of the first cable sections 521 of the first cables 52 are respectively connected to at least one of the first elastic cords 41 that are disposed on the two opposite ends of the cross bar 124 such that the first cable sections 521 of the first cables 52 cross each other at a front side of the support post 123. That is, the second end 524 of the first cable section 521 of the first cable 52 located on the right side of the support post 123 is connected to the second end of the at least one of the first elastic cords 41 located on the left side of the support post 123, while the second end 524 of the first cable section 521 of the first cable 52 located on the left side of the support post 123 is connected to the second end of the at least one of the first elastic cords 41 located on the right side of the support post 123, so that the first cable sections 521 of the first cables 52 form a cross shape at the front side of the support post 123.

It is worth to mention herein that, in actual practice, different thicknesses and different numbers of the first and second elastic cords 41, 42 may be used to obtain different damping effects and to meet the different demands of training, and the damping curve of each of the first and second elastic cords 41, 42 (F=KX, external force is proportional to elongation) is similar to the human muscle strength. The damping can be changed from 10 to 100 kgs. regardless of the user's sex and age. Further, by using the combination of the first cables 52 and the first elastic cords 41 and the combination of the second cable 54 and the second elastic cords 42, the range of different kinds of users is wide.

It should be noted herein that, in the above embodiments, the second and third positioning holes 133, 134 are provided on a right side of the pivot seat 130, but in other embodiments, they may be provided on a left side of the pivot seat 130. In this case, the seat frame 20 can be pivoted and positioned at a left side of the fitness exercise apparatus 100, 100′ (not shown).

The efficiency of this disclosure can be summarized as follows:

1. When performing standing stretching exercises, the first elastic cords 41 and the second elastic cords 42 can be directly stretched without the need to pass through a slide shaft, so that the service life thereof can be effectively prolonged.

2. Through the provision of the cross bar 124 and the pair of support plates 129 on the top portion 122 of the support post 123, the appearance of this disclosure can be enhanced.

3. Depending on the training requirements, the first end 522 of the first cable section 521 of each first cable 52 can be connected to the first end 525 of the second cable section 523 thereof to perform standing stretching exercises. When the first end 525 of the second cable section 523 of each first cable 52 is not in use, the first end 525 thereof can be hooked to the retainer provided on the corresponding left or right side of the hanging rod 125.

4. Because the seat frame 20 is pivotally movable to different angular positions relative to the base member 11, the fitness exercise apparatus 100, 100′ can further provide standing and lying exercises for the user, and has enough space, so that it is convenient for the user to perform different exercise modes.

In summary, the fitness exercise apparatus 100, 100′ of this disclosure has a simple overall structure, and the seat frame 20 can be pivoted to different angular positions relative to the base member 11 through the pivot assembly 13 and can be moved smoothly along the ground surface through the roller 261 attached to the bottom portion of the foot post 26 so as to meet the needs of the user for performing different exercise modes.
